Hello everyone, I am using the na.omit() function on a 785 x 79 matrix. When I restrict the matrix to 10 columns for example it returns me the right result with the na rows deleted: 756 x 10 matrix. But, if I enter the whole matrix it returns me a 64 x 79 matrix, ununderstandable, I have no idea why...Does anyone know what it could be? thanks -- View this message in context:

Dear friends, Hope you are doing well. I am currently using R version 4.3.2, and I have a .xlsx file that has 46 sheets on it. I basically combined all 46 sheets and read them as a single dataframe in R using package rio. I read a solution using package readlx, as suggested in a StackOverflow discussion as follows: df <- read_excel(path = filepath, sheet = sheet_name, guess_max = 100000).

Hi, I have a dataset called 'fish'. fish$Species returns extract 1. When I use fish$Species != c("CRA","PHC"), i.e. I want all species except "CRA" and "PHC", I get extract 2 which is blatantly wrong. Can anyone see what I'm doing wrong?

Hi Wolfgang, from your tusc trace, what's happening is that smbd is hanging on a lock call on the secrets.tdb. Chances are good that either rpc.lockd is not running, or out of sync, etc; I can force this to happen, pretty much the exact same trace, by killing my lockd daemon on the system where I am running samba before I try to start it up. locking problems over nfs is one good reason that

Hi all, I am not exactly fluent in R and I got stuck with this. I would like to compare each elements of a vector A with any of the elements in Vector B. For some reasons it does not work. > StartDate = as.Date("01/10/2007", "%d/%m/%Y") > TimeSpan = seq(StartDate, by = 'days', length = length(myAverageCWVs$X1986)) > TickLabels = c("2007-10-01",

Dear all I'm pretty sure that I'm approaching the problem in a wrong way. Suppose the following character vector: > (x[1:10] <- paste(x[1:10], sample(1:10, 10), sep='')) [1] "a10" "b7" "c2" "d3" "e6" "f1" "g5" "h8" "i9" "j4" > x [1] "a10" "b7"

Dear List, I have been trying to extract associations from a matrix whereby individual locations are within a certain distance threshold from one another. I have been able to extract those individuals where there is 'no interaction' (i.e. where these individuals are not within a specified distance threshold from another individual) and give these individuals a unique Group ID containing
